Huckleberries texture during growth in farm

When farming huckleberries, they will go from seed texture to plant without berries texture. Then they will randomly go back to just the tiled soil texture, but if you use the scythe on the block you will get berries from it. This made it appear that the plants were randomly despawning but I realized they were still there once I went to plant over the block and was told that the block was already occupied.
